DEVICE FOR SECURING BRISTLES IN BRUSHES.

SPECIFICATION forming part of Letters Patent N 0. 725,269, dated April14, 1903. Application filed October 30, 1902. Serial No. 129,478. (Nomodel.)

To all whont it may concern:

Be it known that 1, PAUL MGBIUS, a subject of the Emperor of Germany,and a resident of Erlangen, Bavaria, Germany, have invented certain newand useful Improvements in Devices for Securing Bristles in Brushes, ofwhich the following is a specification.

The invention relates to metallic clamping devices designed to beinserted, together with the bristles, in an opening in the brush blockor head and by compression therein firmly secure the bristles inposition.

The invention is -illustrated in the accompanying drawings, in whichFigure 1 is a sectional view of a portion of a brush-block, showing thebristles and fastening devices in place prior to the device being forceddown to clamp the bristles in place. Fig. 2 is a similar View showingthe device as compressed or forced down to engage the walls of theopening in the block and secure the bristles therein. Figs. 3 and i arevaried views of the modifications.

In the drawings, a designates the bunch of bristles, and 1) brush heador block, having an opening 9 to receive the bunch of bristles.

d represents the clamping or holding devices, which comprise upper andlower crossbands d connected by elbow-shaped bands (i the angles ofwhich extend outwardly in opposite directions.

In using the device the bunch of bristles is placed within the bands andthe assembled parts inserted in the hole g, as done in Fig. 1. The upperband (1 is then forced downwardly by a suit-able device, (not shown,)whereby the sharp points of the elbow-shaped bands are forcedoutwardlyinto engagement with the walls of the opening, as shown in Fig.2.

Instead of having only a single" pair: of elbows between the cross-bandstwo elbows 61 may be, as shown in Fig. 3, connected at the center, or,if desired, the central section may be omitted, as shown in Fig. 4 at 61Having thus described my invention, what I claim is- A device forsecuring bristles in brushheads, comprising upper and lower crossmembers adapted to encircle a bunch of bristles and angular membersconnecting said cross members, substantially as described.

In witness whereof I have hereunto hand in presence of two witnesses.

PAUL MOBIUS.
